Abstract

The seat cushion mounting mechanism comprises a body, a fixing pin, a group of connecting seats, a pushing piece and a control handle. The fixed pin is fixedly arranged on the body, and the connecting seat is pivoted on the body and is provided with a chute. The pushing and propping piece can be slidingly accommodated in the sliding groove of the connecting seat, and the control handle is pivoted with the pushing and propping piece and can rotate relative to the connecting seat so as to drive the pushing and propping piece to extend or retract relative to the sliding groove. When the control handle is not operated and the pushing piece extends out, the pushing piece abuts against the fixing pin, so that the assembling seat cannot rotate relative to the body; when the control handle is operated to retract the pushing piece, the pushing piece is separated from the fixing pin, so that the assembly seat can rotate relative to the body. Therefore, the control handle is operated to drive the pushing piece to abut against or be far away from the fixing pin, so that the rotation or incapability of rotating of the assembly seat relative to the body is controlled.

Description

Seat cushion mounting mechanism

Technical Field

The utility model relates to a seat cushion of a bicycle, a scooter and a walker, in particular to a seat cushion mounting mechanism, which has a special structural design, and can enable the seat cushion to be lifted relative to a seat pipe, so that parts (such as a battery) arranged below the seat cushion are exposed, thereby facilitating a rider to take out the parts and replace the parts.

Background

PCT International publication No. WO2016171532 discloses a bicycle saddle angle adjusting device, which comprises a fixing part, a shell and an adjusting unit. The fixing part is provided with a fixing frame and a command piece which are fixed on the bicycle frame; the shell covers the upper end of the fixing part in a hinged mode. The adjusting unit is arranged on the shell and comprises a stop piece, an elastic device and a control rod, wherein the stop piece surrounds the starting piece, the elastic device provides an elastic force acting on the stop piece, and the control rod is used for adjusting the position of the stop piece. When a rider operates the control lever, the control lever drives the stop member to move away from the contact piece, and simultaneously compresses the elastic device to accumulate elastic force, so that the bicycle seat cushion can rotate relative to the fixing frame of the fixing part to adjust the angle of the bicycle seat cushion. Once the angle of the bicycle seat cushion is adjusted, the rider can release the control lever to release the elastic force of the elastic device to push the resisting piece and the coming piece to approach each other for combination, so that the bicycle seat cushion cannot rotate relative to the fixing frame of the fixing part.

As can be seen from the above, the bicycle saddle angle adjusting device disclosed in the above-mentioned publication is installed between the bicycle saddle and the telescopic saddle tube for adjusting the inclination angle of the bicycle saddle, and the telescopic saddle tube is used for adjusting the height of the bicycle saddle. If a rider wants to take out the parts (such as the battery) in the telescopic seat tube, the seat cushion is detached from the telescopic seat tube, and the parts in the telescopic seat tube can be taken out and replaced. Accordingly, there is still room for improvement in the structure of the bicycle saddle angle adjusting device disclosed in the foregoing.

Disclosure of utility model

In view of the foregoing, it is a primary object of the present utility model to provide a seat cushion mounting mechanism, which has a special structure designed to enable the seat cushion to be lifted up with respect to the seat tube, so as to expose the parts disposed under the seat cushion, thereby facilitating the rider to take out the parts and replace them.

In order to achieve the above-mentioned main purpose, the seat cushion mounting mechanism of the present utility model comprises a body, a fixing pin, a set of seats, a pushing piece, and a control handle. The body is provided with a containing groove. The fixing pin is fixedly arranged in the accommodating groove of the body. The assembly seat can be pivoted on the body between a first position and a second position in a rotating way, and is provided with a chute. The pushing piece is slidably accommodated in the chute of the assembly seat and is provided with a pushing end. The control handle is pivoted with the pushing piece and can rotate relative to the assembly seat between a locking position and an unlocking position so as to drive the pushing piece to move between an extending position and a retracting position relative to the chute. When the assembling seat is positioned at the first position and the control handle is positioned at the locking position to enable the pushing piece to be positioned at the extending position, the abutting end of the pushing piece abuts against the fixing pin to enable the assembling seat to be kept at the first position and not to rotate relative to the body; when the group seat is positioned at the first position and the control handle is positioned at the non-locking position to enable the pushing piece to be positioned at the retracted position, the abutting end of the pushing piece is separated from the fixing pin, so that the group seat can rotate towards the second position relative to the body; when the assembly seat is positioned at the second position and the control handle is positioned at the locking position to enable the pushing piece to be positioned at the extending position, the fixing pin is not blocked by the abutting end of the pushing piece, and the assembly seat can rotate towards the first position relative to the body.

Through the technical characteristics, the seat cushion mounting mechanism of the utility model enables the assembling seat to be unable to rotate relative to the body by operating the control handle to drive the abutting end of the abutting part to abut against the fixing pin, or enables the assembling seat to rotate relative to the body by operating the control handle to drive the abutting end of the abutting part to be away from the fixing pin, and enables the assembling seat to drive the seat cushion to flip upwards relative to the seat pipe, so that parts (such as a battery) arranged below the seat cushion are exposed, and a rider can take out the parts and replace the parts.

Preferably, the abutting end of the pushing element is provided with an abutting concave part for stably abutting against the fixing pin.

Preferably, the abutting end of the abutting piece is provided with a guide cambered surface opposite to the abutting concave part, when the assembly seat rotates from the second position to the first position relative to the body, the guide cambered surface abuts against the fixing pin so as to enable the abutting piece to retract relative to the sliding groove until the abutting concave part abuts against the fixing pin. Therefore, the pushing piece can automatically reset through the guide of the guide cambered surface, and the pushing concave part is pushed against the fixing pin again, so that a rider does not need to continuously operate the control handle to rotate from the unlocking position to the locking position.

Preferably, the assembling seat is provided with a fixing hole; the control handle is provided with a handle part, a slot arranged on the handle part, a safety plug pin and an elastic piece, wherein the safety plug pin can be glidingly arranged on the slot between an insertion position and a release position, and the elastic piece provides an elastic force to force the safety plug pin to face the insertion position; when the safety bolt is positioned at the inserting position, the safety bolt is inserted into the fixing hole of the assembling seat so as to keep the control handle at the locking position, and when the safety bolt is positioned at the disengaging position, the safety bolt is disengaged from the fixing hole of the assembling seat so as to enable the control handle to be capable of moving from the locking position to the non-locking position. Therefore, the safety bolt is used for preventing a rider from touching the handle part of the control handle by mistake, so that the safety in use is improved.

The detailed construction, features, assembly or use of the seat cushion mounting mechanism provided by the present utility model will be described in the detailed description of the embodiments that follow. However, those skilled in the art will appreciate that the detailed description and specific examples, while indicating the utility model, are given by way of illustration only and are not intended to limit the scope of the utility model as defined in the appended claims.

Detailed Description

Applicant hereby gives notice that throughout this specification, including the examples presented below and claims, directional terms are used to refer to the directions in the drawings. Next, in the embodiments to be described below and the drawings, the same reference numerals denote the same or similar components or structural features thereof.

Referring to fig. 1, a seat cushion mounting mechanism 1 according to a first embodiment of the present utility model is disposed between a seat cushion 10 and a seat tube 13, and the seat cushion 10 shown in fig. 1 has a cushion body 11 and two seat bows 12 disposed at a bottom of the cushion body 11 at intervals. In this embodiment, the seat cushion 10 may be, but is not limited to, one of the components of a bicycle, scooter, or walker.

As shown in fig. 2 and 3, the seat cushion mounting mechanism 1 of the first embodiment of the present utility model includes a main body 20, a fixing pin 30, a set seat 40, a pushing member 61, a control handle 65, an elastic member 68, and a brake lever 69.

The body 20 is integrally connected to the top end of the seat tube 13, and the body 20 may be connected to the top end of the seat tube 13 by bolts or other fastening methods, which are not limited herein. The body 20 has a first pivot hole 21 therethrough, a receiving slot 22 adjacent to the first pivot hole 21, and two holes 23 disposed opposite to and communicating with the receiving slot 22.

The two ends of the fixing pin 30 respectively penetrate through the holes 23 of the body 20 and are fixedly arranged in the accommodating groove 22 of the body 20.

The connecting seat 40 has a collar 41, the collar 41 has a sleeve hole 42, a chute 43 adjacent to the sleeve hole 42, and a slot hole 44 transversely connected to the chute 43, and the slot hole 44 has a high end H and a low end L. The connecting seat 40 further has two pivoting portions 45 extending from the collar 41, and each pivoting portion 45 has a second pivot hole 46.

As shown in fig. 2, in the actual assembly, the second pivot holes 46 of the assembling base 40 correspond to the first pivot holes 21 of the body 20, and two pivot rods 47, 48 are inserted through the first pivot holes 21 and the second pivot holes 46, so that the assembling base 40 can be pivoted on the body 20 between a first position P1 shown in fig. 3 and a second position P2 shown in fig. 5. With continued reference to fig. 2, a support tube 50 is inserted through the sleeve hole 42 of the collar 41 of the assembly seat 40, and the collar 41 is tightened by a screw S, so that the support tube 50 is fixed in the sleeve hole 42, then two clamping pieces 51 are respectively abutted against two ends of the support tube 50, and a screw 52 is used to insert and fix the clamping pieces 51 and the support tube 50, so that the clamping pieces 51 respectively clamp and fix the seat bows 12 of the seat cushion 10 shown in fig. 1.

The pushing member 61 has a mounting end 62, an abutting end 63, and a through hole 64 disposed between the mounting end 62 and the abutting end 63. As shown in fig. 3, the abutment end 63 has an abutment recess 631 for abutting against the fixing pin 30, and a guide cambered surface 632 opposite to the abutment recess 631.

As shown in fig. 2, the control handle 65 has a handle portion 66 and two pivot holes 67 disposed at one end of the handle portion 66, wherein the handle portion 66 has a hollow slot 661 through which the screw S passes.

In this embodiment, the elastic member 68 is a compression spring. As shown in fig. 3, the elastic member 68 is accommodated in the sliding groove 43 of the socket 40, one end of the elastic member 68 abuts against the bottom of the sliding groove 43, and the other end of the elastic member 68 abuts against the mounting end 62 of the pushing member 61, so as to provide an elastic force to the pushing member 61.

As shown in fig. 2 and 3, in actual assembly, the elastic member 68 and the pushing member 61 are sequentially placed into the sliding slot 43 of the assembling seat 40, the through hole 64 of the pushing member 61 corresponds to the long slot 44 of the assembling seat 40, the pivot holes 67 of the lever 65 correspond to the long slot 44 of the assembling seat 40, then the detent lever 69 sequentially passes through one of the pivot holes 67 of the lever 65, the long slot 44 of the assembling seat 40, and the through hole 64 of the pushing member 61, and then passes through the other pivot hole 67 of the lever 65 and is fixed by a fixing piece C, so that the lever 65 and the pushing member 61 are pivoted to each other to rotate relative to the assembling seat 40 between a locking position P3 shown in fig. 3 and an unlocking position P4 shown in fig. 4. The lever 65 can drive the detent lever 69 to move laterally between the high end H and the low end L of the elongated slot 44 of the socket 40 during rotation, and further drive the pushing member 61 to move between an extended position P5 shown in fig. 3 and a retracted position P6 shown in fig. 4 relative to the chute 43 of the socket 40 via the detent lever 69.

In actual operation, as shown in fig. 3, when the rider has not pulled the handle 66 of the control handle 65, the seat 40 is located at the first position P1 and the control handle 65 is located at the locking position P3, and the detent lever 69 is located at the lower end L of the long slot 44 of the seat 40, so that the pushing member 61 is located at the extended position P5 and stably abuts against the fixing pin 30 with the abutting recess 631, so that the seat 40 is kept at the first position P1 and cannot rotate relative to the body 20, and thus the positioning effect can be achieved, and the rider can stably sit on the cushion body 11 of the seat cushion 10 shown in fig. 1.

Continuing with the above description, when the rider applies a force to pull the handle portion 66 of the control lever 65 upward, the control lever 65 is rotated from the locking position P3 shown in fig. 3 to the unlocking position P4 shown in fig. 4, the detent lever 69 is displaced from the low end L to the high end H of the slot 44 at this time, and the pushing member 61 is moved from the extended position P5 shown in fig. 3 toward the retracted position P6 shown in fig. 4, so that the abutment recess 631 of the pushing member 61 is separated from the fixing pin 30, and the elastic member 68 is compressed by the disposition end 62 of the pushing member 61 to accumulate the elastic force.

In this case, as shown in fig. 4, the body 20 and the socket 40 are in an unfixed state, that is, the socket 40 can rotate from the first position P1 shown in fig. 4 to the second position P2 shown in fig. 5, and different pivot angles are formed between the socket and the body 20. In addition, the seat 40 can also drive the seat cushion 10 to flip upwards to the state of fig. 6, so that the parts (such as the battery) arranged below the seat cushion 10 are exposed, and the rider can take out the parts and replace the parts.

Once the parts are replaced, the force applied to the shank 66 of the lever 65 is released, so that the lever 65 rotates from the unlocked position P4 of fig. 5 to the locked position P3 of fig. 7, the elastic force released by the elastic member 68 acts on the pushing member 61, so that the pushing member 61 is displaced from the retracted position P6 of fig. 5 to the extended position P5 of fig. 7, the socket 40 rotates under the action of gravity from the second position P2 of fig. 7 toward the first position P1 of fig. 3, the fixing pin 30 is not abutted by the abutting end 63 of the pushing member 61, as shown in fig. 8, and when the socket 40 continues to rotate toward the first position P1, the guide cambered surface 632 of the pushing member 61 abuts against the fixing pin 30, and the pushing member 61 is retracted relative to the chute 43 guided by the guide cambered surface 632 until abutting the concave portion 631 abuts against the fixing pin 30 again (as shown in fig. 3), so that the body 20 cannot rotate relative to the socket 40 and is kept at the first position P1. In this way, the pushing member 61 can be automatically reset by the guiding of the guiding cambered surface 632, so that the pushing recess 631 is pushed against the fixing pin 30 again, and the rider does not need to continuously operate the control handle 65 to rotate from the unlocking position P4 shown in fig. 5 to the locking position P3 shown in fig. 3.

However, the seat cushion mounting mechanism 1 is not limited to the disclosure of the present embodiment, and referring to fig. 9, the seat cushion mounting mechanism 2 of the second embodiment of the present utility model is substantially identical to the first embodiment in terms of structure, and the main difference is that the present embodiment provides another assembling seat 70 and a control handle 80. In the present embodiment, the socket 70 has a fixing hole 71 at the bottom, and the lever 80 has a handle 81, a slot 82 at the handle 81, a safety latch 83, and an elastic member 84. The safety latch 83 is slidably disposed in the slot 82 between an insertion position P7 shown in fig. 9 and a release position P8 shown in fig. 10, and the elastic member 84 is received in the slot 82 and provides an elastic force to hold the safety latch 83 in the insertion position P7.

In actual operation, when the rider applies a force to pull the safety latch 83 downward, the safety latch 83 is displaced from the insertion position P7 shown in fig. 9 to the release position P8 shown in fig. 10, the safety latch 83 is released from the fixing hole 71 of the socket 70, and the elastic member 84 is compressed by the safety latch 83 to accumulate elastic force, so that the control handle 80 can rotate relative to the socket 70. Once the rider releases the force applied to the safety latch 83, the elastic force released by the elastic member 84 acts on the safety latch 83 to displace the safety latch 83 from the release position P8 shown in fig. 10 to the insertion position P7 shown in fig. 9, so that the safety latch 83 is inserted into the fixing hole 71 of the socket 70, and the lever 80 cannot rotate relative to the socket 70.

Thus, the design of the safety latch 83 and the elastic member 84 provided in the present embodiment can prevent the rider from touching the handle 81 of the control handle 80 by mistake, so as to improve the safety in use. The manner of operating the control handle 80 to rotate the assembly seat 70 relative to the main body 20 is exactly the same as the previous steps, and therefore, the description thereof is omitted.

To sum up, in the seat cushion mounting mechanism 1, 2 of the present utility model, the lever 65, 80 is operated to drive the abutting end 63 of the pushing member 61 to abut against the fixing pin 30, so that the assembling seat 40, 70 cannot rotate relative to the main body 20, or the lever 65, 80 is operated to drive the abutting end 63 of the pushing member 61 away from the fixing pin 30, so that the assembling seat 40, 70 rotates relative to the main body 20, so that the assembling seat 40, 70 drives the seat cushion 10 to flip up relative to the seat tube 13, and the part (such as a battery) arranged below the seat cushion 10 is exposed, so that the rider can take out the part and replace the part.
